Arc'teryx Thorium Hoody Men's Insulated Down Jacket

The Arc'teryx Thorium Hoody is a men's belay jacket built for cold-weather climbing, with bold baffling and 750-fill European grey goose down for reliable warmth. The rugged Arato 30 mini-ripstop nylon shell stands up to sharp rock, while Down Composite Mapping places Coreloft 80 synthetic insulation in moisture-prone areas such as the hood, shoulders, under the arms, around the mouth, and at the cuffs.

Climbing-specific details include a two-way front zip for harness access and oversized internal dump pockets to keep shoes warm between burns. The updated version adds increased down fill, a boxier fit for better layering, and larger baffles that boost insulation. It is finished with an FC0-DWR treatment that repels light rain or snow, and it is Fair Trade Certified and made with bluesign approved materials.
